TWISTING-MACHINE.

Specification of Letters Patent.

Patented Oct. 1, 1912.

Application filed November 27,1911. Serial No. 662,608:

To all whom it may concern:

Be it known that I, ISAAC I1. VVoLKoW, a citizen of the United States,residing at Louisville, in the county of Jefli'erson and State ofKentucky, have invented certain new and useful Improvements inTwistingldachines, 'of which the following is a specification.

The present invention is a machine for making the hair structuredescribed in my Patent No. 1,004,130, dated September 26,

1911, said structure consisting of strands of braided twine or othercord which are twisted together, and between which twisted strands areplaced and held tufts of hair', wool or cotton.

It is the object of the invention to provide a simple and eificientmachine for the purpose stated, and to this end it consists m a novelconstruction and arrangement of parts to be hereinafter described andclaimed.

In order that the invention may be better understood, reference is. hadto the accompanying drawings in which- Figure 1 is a side elevation ofthe machine; Fig. 2 is an enlarged cross-section on the line 2-2 of Fig.1; Fig. 3 is a plan View of the track hereinafter referred to; Fig. 4 isan enlarged plan view, partly broken away, of the drive gear; Fig. 5 isan end View of the drive gear, and Fig. 6 is a section on the line 6--6of Fig. 4:.

Referring specifically to the drawings, 10 denotes a suitable base whichsupports the mechanism. At one end of the base are mounted bearings 11and 12 which support the various shafts of the gearing tobe presentlydescribed.

In the bearing 11 is journaled a hollow, horizontal shaft 13 carrying atone of its ends a bobbin-frame 14. In this frame are journaled twospindles 15 extending parallel to the shaft 13 and carrying the bobbinsor spools of cord 16. The spindles are rotatable in the same'directionthrough a gear 17 in mesh with gears 18 on the respective spindles. Thegear 17 is fast on a shaft 19 passing loosely through the shaft 13. -Thespindles carry arms 20 having spring tension devices 21 to which thecord passes from the spools. From the tension devices the cord extendsto the outer end of the spindles and is threaded through an eye 22therein.

At 23 is indicated a main drive shaft A spindles 15.

which receives motion from a suitable source of power which latter neednot here be illustrated as it forms no part of the present invention. Onthis shaft is fast a pinion 24 which is in mesh with a spur gear 25loosely mounted on a hollow shaft 26 supported at its ends in thebearings 11 and 12. In the hub 27 of the gear 25'is a cavity 28 havingin one of its end walls a key-way or slot 29. In the bore of the shaft26 is mounted, to slide lengthwise therein, a stem 30 carrying a key 31which extends sidewise throu h a longitudinal slot 32in the side of saids aft and enters the cavity 28. 'On the shaft 26 is also loosely mounteda spurgear .33 having in its hub '34 a key-Way 35 which is opposite andadjacent to the key-way 29. When the stem 30 is actuated to insert thekey 31 into the key-Way 29, the motion of the gear 25 is transmitted tothe sleeve 26, and when the key is inserted into the key-Way 35 also,the motion of the sleeve is transmitted to the gear 33. A suitableoperating lever 36 is provided for actuating the stem 30 to engage thekey with the key-ways as herein described and for disengaging the same.The width of the key is such that it may seat in both key-ways at. thesame time, and the length of the slot 32 is such as to permit the key tobe moved a sufficient distance to cometo this positiop.

On the shaft 26 is fast a pinlon 37 which is in mesh with a spur gear 38which latter, in turn, is in mesh with a pinion 39 fast on the shaft 19,whereby the motion of the shaft 26 is transmitted to said shaft 19, andthrough the gears 17 and 18 to the The gear 38 is supported by thebearing 12.

The gear 33 is in mesh with a pinion 40, which latter is in mesh with as ur gear 41 fast on the shaft 13. The pinion is supported by thebearing 11. This gearing transmits the motion of the shaft 26 to thealso have'an orbital motion in the opposite direction, in view of whichthe cords are individually twisted in one direction while theyaretwisting on themselves in the other lid fit?

direction. The gear ratio is such that the spindles rotate faster thanthe bobbinframe, I

The tufts of hair, wool or cotton are placed at suitable intervalsbetween the twisted cords which produces the structure described in mypatent hereinbefore referred to. The tufts may be fed between the; cordsby hand; or an automatic feeding device may be provided.

A traveling carrier is provided whereby the finished article is carriedforward away from the machine, and the cords are unwound from thebobbins. This carrier is constructed and arranged as follows: On thebase 10 are supports 42 which carry sprocket wheels 43. Four of thesesprocket wheels are provided and they are so arranged that the endlesschain 44 which connects the same travels in a substantially rectangularpath, the upper run of the chain being horizontal, and the chaintraveling in a direction so that said upper run travels forward, or awayfrom the twisting mechanism. On the shaft of one of the sprocket wheelsis a worm gear 45 which is in mesh with a worm 46 on a shaft 47 on whichis fast a large spur gear 48 which latter is in mesh with a pinion 49 onthe shaft 13. It will therefore be evident that the gear of the twistingmechanism, through the worm gearing herein described, also drives thecarrier, the worm gearing transmitting motion to the sprocket wheel in adirection to drive the chain in the proper direction.

The chain 44 carries grippers which are constructed as follows: To ablock'50 are pivoted, as indicated at "51, two opposed jaws 52 which areheld 0 en by a spring 53. The block is connecte to the chain so as totravel with it. Above the upper run of the chain is mounted a trackcomprising two spaced parallel bars 54 extending arallel to the chainand having flared en 55. The bars are so located that the grippers entertherebetween, and the space between said bars is such that they closethe jaws when the latter come in contact therewith. On the outer surfaceof the jaws are antifriction'rollers 56 which-roll along the innersurface of the bars. The jaws 52 close when they enter the contractedspace between the bars 54, and upon leaving the same they are opened bythe spring 53. A suficient number of grippers are provided so that thefinished article may be gripped at two points as clearl shown in Fig. 1.The shaft 47 is provided with a clutch 5?, an to the shaft of one of thesprocket wheels 48 is fitted a crank handle 58.

The machine operates as follows: The two cords are threaded through thetension devices 21 and the eye 22 of the spindles 15, and their ends aretied together. The cords are then pulled out until the lmot is above thecarrier, and held there while the shaft 47 is disconnected from thedrive gear by operating the clutch 57. The crank handle 58 is-nowoperated to position one of the grippers so that it may be engaged withthe knotted end of the cords. The clutch 57 is now operated to connectthe shaft 47 to the drive gear. The motor or other source of power beingstarted, the stem 30 is pulled rearward until the key 31 enters thekeyway 29, whereupon the spindles 15 are set in motion to give theindividual twist to the cords. After a proper twist has been given thecords, the stem 30 is pulled still further until the key 31 enters thekey-Way 35 also, whereupon the bobbin-frame 14 is also putin motion totwist the cords upon themselves. The, tufts of hair or other materialare now placed between the cords as they are twisting on themselves, andthe finished article is carried away by the traveling grippers as fastas it is formed, without any attention from the operator. At the forwardend of the track the gripper jaws open and release the article which isat the same in stant picked up by a gripper entering the track at therear. The drive gear of the grippers will be so designed that thegrippers are carried forward at the proper rate of speed.

The machine can be run at any speed desired, and by means of the lever36 is always under control of the operator.. The frame of the machinemay also be widened and as many more spindles provided as are necgssaryto produce any kind of twisted cor It will, of course, be understoodthat the machine as illustrated can be varied in construction withinconsiderable limits, without departure from the spirit of the invention.
